My main point was that proof of stake protocols exist, and that Bitcoin being inefficient does not mean all cryptos are inefficient. It's also interesting how you ignore even more "painfully obvious" comments on the topic at hand:
1st is saying blockchain is worthless because it is inefficient. This correlates to saying democracy is worthless because a dictator could make all the same decisions but much quicker.
Well you were wrong in what you posted. If you're going to make a point, regardless of what that point is, you should post information that is actually factual. Also, how do you even know he was referring to energy usage? He didn't say anything about energy usage at all. He also didn't say bitcoin specifically, he said blockchains. Blockchains
are inefficient databases architectures. That's because they're broadcast networks. They must be in order to maintain decentralization. That means inefficiency is inherent to being a blockchain. If a blockchain isn't decentralized it has no benefits over a typical relational database like SQL. Therefore it is inefficient by design in the sense that you can't allow for every transaction in the world that could be broadcast confirmed on a blockchain. It's simply not feasible. Doesn't matter whether the consensus mechanism is PoW or PoS, the same holds true.
Anyways, in regards to energy usage (if that's indeed what is meant by "inefficient" here), bitcoin has several downward pressures applied to it from an energy consumption perspective. While price currently provides an upward forcing in the amount of energy it consumes, things like ASIC efficiency increases, the difficulty adjustment, and the block reward halvings provide downward forcings on that energy usage. I don't think it is accurate to call bitcoin inefficient from an energy usage standpoint. First off, a vast majority of bitcoins in circulation were mined at a time when energy usage was small and mined with CPU/GPUs. Therefore the ratio between the amount of energy spent per unit of value for bitcoin is very small and its large energy consumption during the production period of bitcoin's life will be very fleeting.
This is because of bitcoin's supply halvings that take place every 4 years. In order for the price to have a continued upward pressure on its energy usage, the price would need to continue to be exponential well into the future to counteract the newly created supply being cut in half every 4 years. So either bitcoin becomes extremely valuable in the future and thus provides humanity a lot of value for its energy use in comparison, or miners begin to derive a majority of their revenues from fees rather than block subsidy. A combination of both those things is likely to occur, but it is only a matter of time before miners
will derive a majority of their revenue from fees as bitcoin transitions into a fee based mining incentive structure.
Bitcoin profit margins are typically pretty slim due to the intense global competition involved. Therefore as the market continues to move to a fee based incentive, bitcoin's energy usage will be as a direct result of economic activity that takes place on the bitcoin blockchain. Every fee paid to conduct a transaction will result in a nearly equivalent amount of the cheapest global energy consumed. There is no monetary system that can come close to even claiming such an efficiency. Bitcoin will not need to deal with any of the losses of energy found in traditional systems such as lost productivity, bureaucratic waste, poor governance, logistics, regulatory overhead, etc. If I need to spend a $100 fee to send a bitcoin transaction, that $100 fee will result in nearly $100 of some of the cheapest energy on the planet being consumed to confirm my transaction. Furthermore, 1 transaction on the bitcoin network does not equal 1 payment. Bitcoin's base layer is a settlement layer. 1 transaction likely equals many payments (potentially thousands or millions) as a transaction can consist of many batched transactions or a settlement transactions for the lightning network settling many millions of transactions. The efficiency here at the base layer from an energy standpoint is something that will actually be pretty outstanding as time goes on.
Furthermore, due to mining competition, ASIC efficiency increases, and the difficulty adjustment, mining bitcoin must take place with the cheapest electricity found globally. That means that as renewable energy continues to become the dominant cheap form of energy in all global markets, bitcoin mining's transition to an all renewable network will take place faster than any other industry so long as fossil fuel subsidies aren't increased to keep pace with renewable advancements.
IMO, because of the above features of bitcoin, I don't think it is fair to call bitcoin inefficient from an energy perspective. I feel it is actually quite efficient in that regard.
It's also "painfully obvious" when posters equate a normal brokerage account with an offshore crypto exchange caught violating U.S. banking laws, like your best example "Bitmex" back in this post:
There's also no counter-weight to the optimism. If someone thinks Tesla is overpriced, they can short the stock or buy PUT options. If someone who doesn't own Bitcoin thinks it is about to fall ... you can't short it in your brokerage account. There's no options to buy. So the only people who can express their views are buyers.
Ya, that's not true. You can short bitcoin on several exchange/broker websites (BitMex probably being the largest). I track many of the larger transactions that take place and there were several very large liquidated shorts that just took place after bitcoin just breached $35k ($6.4M, $2.4M, and $1.3M). In fact, short squeezes in bitcoin are often what cause many of the larger upside swings. Long story short though is that not many choose to short bitcoin because it is absolutely stupid to do so with something that is so lopsided toward buy demand and who's upside is so tremendously high.
I said "you can't short it in your brokerage account", and BitMex is not a brokerage. If someone buys PUT options on TSLA, that goes to the CBOE... there's a well established system of what happens to enforce the contracts.
BitMex is registered in an island off the coast of Africa. To quote Wikipedia:
"BitMEX was founded in 2014 by Arthur Hayes, Ben Delo, and Samuel Reed, with financing from family and friends."
...
"On October 1, 2020, Hayes, Reed, Delo, and Gregory Dwyer were indicted on charges of violating the U.S. Bank Secrecy Act and conspiracy to violate that law, arising from allegations that the four failed to implement anti-money laundering measures"

Haha, you literally dug up a post from 4 months ago. I'm flattered that you remember all my posts like that. I really am. But can I ask that if you're going to dig up old posts like that, can you at least quote the entire conversation?
No, you can't short bitcoin in your typical brokerage account.
Your original point was simply that you were implying that there is no downwards pressure on bitcoin to counteract all the demand, when there is. There are several places you can short bitcoin.

You're right that I exaggerated in my original post, saying there was "no place" to short bitcoin. But I didn't expect mainstream investment choices to be put on a par with websites like the one you gave as an example.
I wasn't equating BitMex to traditional mainstream financial brokers. I was simply countering your factually incorrect claim that there is nowhere to short bitcoin or that there isn't any downward pressure on bitcoin's price like you insinuated by saying: "There's also no counter-weight to the optimism." That's not true at all and there have been many short squeezes throughout bitcoin's life where the price has skyrocketed in the matter of an hour as shorters get liquidated to the tune of millions/billions of dollars. Therefore it stands to reason that if there is a major price movement upwards due to shorts getting liquidated, that means there was that amount of downward pressure being applied to the market while those shorts were in play.
No you can't short bitcoin in your typical mainstream brokerage account. I never equated the places you can short bitcoin at to your traditional mainstream brokerage. But at the same time you also can't buy actual bitcoin at market price at your typical brokerage either, so I am not sure what point you're trying to make by pointing that out when there really isn't unequal balance in the market in that regard. Many of the places you
can actually buy bitcoin at you can also short bitcoin and I provided a couple links with references in that post from 4 months ago that you conveniently left out.
